5. 6. mark B Braids with parallel twine cores Tapering the end of the cover and brushing the splice area smooth The end of the cover is now tapered progressively along its complete length. Then the slack is stroked out of the cover, beginning at “B“, in the direction of the slipknot, after that, the protruding strand ends and or cover ends are Splicing in a thimble If a thimble needs to be spliced in, this is inserted in the eye shortly before the last milking of the slack. After this, the remaining slack of the cover is stroked into the direction of the eye. Pulling of cover tail into the cover and tapering Unravel the end of the cover up to “A“. Then insert the splicing needle into the cover about 20 cm from “B“. The needle re-emerges at “B“. Now place the tail of the cover in the slot and pull the cover into the cover braid. mark B Eye-Splice cropped close to the point of emergence. Once more, stroke the splice area smooth, until the yarn ends disappear into the braid. Ropes with high modulus fibre cores e.g. Vectran, Dyneema, Dyneema Classic, Dynamix, Dyna Lite, Caribic Color Eye-Splice Method 1, Core-to-Core Splice Method 2, Core-to-Core Splice 7. Construction and Applications These ropes are highly specialised constructions for the most demanding applications. Braided cores of high modulus fibres, such as Dyneema, Vectran or Kevlar feature technical characteristics, in terms of break load and stretch behaviour, that can be an improvement on those of a steel wire rope. The load-bearing core has a braided protective cover of high tenacity polyester. An additional intermediate cover over the core improves friction between the load bearing centre and the protective cover for more efficient use in stoppers. <strong>Splicebook</strong> 044|45 This section of our splice book introduces advanced splicing techniques, which require close adherence to the instructions and care in their application. In this way splices can be produced that will transfer the physical properties of these high quality lines into practical use on board resulting in the ultimate performance, durability and safety for halyards, sheets, guys and other applications.
1. Ropes with high modulus fibre cores Eye Splice, Method 1 With all ropes made of high modulus chemical fibres, the load is carried almost exclusively by the core. The cover provides protection against light and abrasion. Consequently during splicing, the core must be spliced back into the core and the cover bound into the eye. There are basically two splicing possibilities. Preparation of the rope end and measuring of the eye The rope end must be taped not heat sealed. Should it have been heat sealed, then that section must be cut off. In the case of our rope types Vectran and Dyneema there is a white staple fibre cover braided around the core proper. This intermediate cover must be removed from the entire area of the splice. Milk the cover over the core to such a length that about six fid lengths of the core can be seen. The intermediate cover is then cut off at that point and removed from the core. The remaining end of the intermediate cover is fixed to the core by means of a layer of tape. The cover is then milked back to cover 2 fid lengths Eye-Splice, Method 1 These differ essentially in the whereabouts of the end of the cover. Both methods are described here. Both methods presume basic knowledge and require care. The second one is the more elegant of the two but requires more time. The splicing tools are the same as those used for all braided ropes. mark 2 mark 1 the end of the rope. This step is not necessary with Dynamix or Aramid rope, as the intermediate cover is missing. Now, a three-quarter fid length of the core is cut off, and the cover brought back to the new core end. A layer of tape seals the end of the rope. The cover now has some slack, which is stroked away from the rope end. Measure two fid lengths from the end of the rope and mark position 1. Form the eye to the desired size and mark position 2. Tie a slipknot into the rope about five fid lengths from mark 2. 2. Ropes with high modulus fibre cores Precise tapering of the core At the position marked 1, the core is now pulled out from beneath the cover. This may prove more difficult with a 32 braid. The fid and tip of the pusher are appropriate here, in forming the hole in the cover. Care must be taken, that the core is not disarranged respective to the cover between mark 1 and the slipknot. It is advisable to fasten the braids at both points with a spike, nail or similar object pushed through them. A layer of tape seals the core end. Now we come to the precise tapering of the core. This step is decisive for the strength, quality and appearance of the splice. Inspect the core braid closely. It will consist either of simple yarns, or twofold, threefold or even fourfold yarns. This braidwork must now be halved over a long section. At this stage, a length of six braids lying next to each other must be measured from mark 1 on the core Eye-Splice, Method 1 mark 2 6 braids mark 1 <strong>Splicebook</strong> 046|47 mark 1 (refer to the diagram, where this procedure is outlined clearly). The tapering is to be done from the sixth braid onwards. First taper one braid lay direction i. e., those braids running clockwise. Halve the braids according to the diagram. Where the braid consists only of one yarn, “one over the other“ yarn is cut and removed from the braid; with 2 yarns, every other yarn is removed alternatively braid by braid. Where there are three yarns, first two yarns are cut and removed, then from the next group, one yarn is severed and pulled out etc. When all the yarns running in one direction have been halved (e.g. clockwise), then the same procedure is carried out with those yarns running in the other direction – refer to diagram. The tape on the end of the core holds the residual braid together adequately during this procedure.
